摘要

制备并研究了以金属纳米颗粒（金、钯、铂）修饰的阳极单壁二氧化钛纳米管为基础的光催化剂。金属纳米颗粒的尺寸范围为 3 至 15 nm。纳米管的管壁厚度从 14 纳米到 17 纳米不等。研究证实，含金、钯、铂的光催化剂在乙醇完全分解反应过程中会产生乙醛。此外，在含有钯和金纳米颗粒的氧化钛纳米管中还会产生甲烷。我们首次获得了用 Pd 和 Au 纳米粒子修饰的多功能 TiO 纳米管，可用于空气净化和碳氢化合物燃料前体的生产。

Synthesis and investigation of multifunctional TiO2 photocatalysts modified by metal nanoparticles

Photocatalysts based on the anodic single-walled titania nanotubes modified with metal nanoparticles (Au, Pd, Pt) were prepared and investigated. The metal nanoparticles sizes are in a range from 3 to 15 nm. The wall thickness of the nanotubes varied from 14 to 17 nm. It is established that photocatalysts with Au, Pd, Pt produce acetaldehyde during complete ethanol decomposition reaction. Additionally the formation of methane occurs in the TiO₂ nanotubes with Pd and Au nanoparticles. We obtained firstly the multifunctional TiO₂ nanotubes modified with Pd and Au nanoparticles for use both in air purification and in the production of hydrocarbon fuel precursors.
